This invention relates to pocket carried implements, and moreparticularly to the clips used to prevent them from becoming loosenedand lost.

The usual type of clip consists of a strip of spring metal, fixedlyengaged at one end to the body, or cap, of the implement, to extendalongside, and terminate in a nodula hump, disposed outside the pocket.7

This arrangement permits the implement to sway in the pocket, bypivoting on the hump, and, as the hump is smoothly rounded, fails toprovide such secure gripping effect as is desirable.

Having this matter in mind, it is an object to provide a clip that canbe relied upon to retain an article to which it is affixed, safely andsecurely in a pocket, preventing it from side swaying or swingingmovement.

Another purpose is to produce a clip having a concealed, undulatedspring strip, provided with defined corrugations adapted to forciblygrip the pensive construction, ease of application and long continuedservice, are accomplished by the novel and practical construction andarrangement of simple parts, hereinafter described and illustrated inthe accompanying drawing, constituting a graphical component of thisdisclosure, and in which:

Figure 9 is a plan View of the blank from which the clip in Figure 7 isformed.

In Figure 1 of the drawing, a fragmentary portion of a garment isdesignated by the numeral l5, having a pocket, as indicated by the barl6, above which protrudes the cap I! of a writing implement l8, as thefountain pen shown. This is, however, to be regarded only as suggestive,rather than restrictive, of the types of pocket carried articles towhich the clip may be applied.

Such clips are attached to an object by any preferred means, asencircling bands, in-set rings, in-bent or out-turned prongs, etc. whichform no part of the present invention, the showing being merelyillustrative.

The device consists of a stamping from sheet spring metal, shaped toproduce a bar 20 having down-turned lateral edges 2|, their rearportions provided with prongs 22, or other preferred fastening means,whereby the bar is rigidly fixed to an article, as the pen cap IT.

The extreme rear end 23 of the bar is downturned to contact the cap,while its main front portion is convexly curved in cross section to itsre-entrantly turned Width reduced front end 24, where the edges of themetal are bent inwardly to form a smooth-faced socket 25 adapted tonormally contact the cap ll under spring pressure.

Inserted in the socket is an end 28 of a spring strip 29 shaped topresent transverse, wave-like undulations 30, preferably varying insize, the coarser being near the socket, while the finer gradually blendinto the flattened portion 3| of the strip, which is entered between thechan nelled edges 2| of the bar.

It will be understood that these undulations yield readily when the clipis passed over the pocket material, as at MS, as does also the loop 25;thus the device is easy to attach in a manner to clamp the pocketmaterial with sufficient tension to avoid accidental displacement, whilethe corrugations prevent side swaying movement of the article in thepocket.

In addition, the strip 29 may be further provided with non-slip means,as the fine checkered corrugations 32, shown in Figure 5, or a roughenedsurface 33, as in Figure 6, prior to undulating it.

Figure '7 shows a modified form of clip in which the down-turned edges2! are provided with a series of serrations 35 as best seen in the blankof Figure 9.

A further modified form of clip is disclosed in Figure 8, in which thebar 20 is shaped to form a socket 25 at its free end to receive a strip40 having undulations 4|, the strip being free between the down-turnedsides 2! of the bar and having an integral connection 42 with it at theend adjacent the prongs 22, while the opposite, free end of the strip isentered into the socket.

A pocket carried implement clip comprising a 10 unitary spring barhaving one end bent at a right angle and means combined therewith forattachment to an implement, a re-entrantly inturned loop socket at theopposite end presenting a smoothly curved under surface to contact theouter side of a pocket, a spring strip having one end abutting the innersurface of the bar angle, its opposite end being curved to engage insaid loop socket, and a plurality of teeth formed transversely in saidstrip.
